ELECTROCHEMICAL ELEMENT, SOLID OXIDE TYPE FUEL BATTERY CELL, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention implements an electrochemical element having a dense electrolyte layer and having excellent durability and rigidity; a solid oxide type fuel battery cell; and a method for manufacturing the electrochemical element and the solid oxide type fuel battery cell. The electrochemical element has a metal substrate 2 having a plurality of through-holes 21, an electrode layer 3 provided on the front-side surface of the metal substrate 2, and an electrolyte layer 4 provided on the electrode layer 3. The through-holes 21 are provided to pass through the front-side surface and rear-side surface of the metal substrate 2, the electrode layer 3 is provided on a region larger than a region in which the through-holes 21 in the metal substrate 2 are provided, and the electrolyte layer 4 has a first portion 41 covering the electrode layer 3 and a second portion 42 contacting the front-side surface of the metal substrate 2.
